This has been a fun experiment! I'm available if anyone has any questions as well as other folks from the Suborbital team—cohix, nyahmacklindev, and jagger27.

Yep, thrilled to be here and help folks out however we need :)

What's the use case for this?

One of the first things we've used it for internally is to run one-off isolated tests on WebAssembly modules instead of feeding them through a production Atmo[0] instance. It basically serves as a dumb pipe for feeding data in and out of any Wasm module built for Reactr[1].

So, from what I understand Atmo and Reactr are about building an app as functions, and then Atmo and Reactr takes care of invoking them when they're needed? Is that correct?

Yes that’s right.
